<div>Bill, I am using a Comet dual antenna - not sure about the model, but it's based on a 2 meter half wave so it doesn't require a ground plane. I have it mounted on a luggage rack on the trunk of a Goldwing bike. I'm not sure how high the W4IAX digi antenna is, but hte W4IAX repeater antenna is almost 1,000 ft above sea level - that is right here on the coast.

<div>I expect the the pattern is decent because I talk thru the repeater on the way to work and back. I have full quieting signal on this same radio via the repeater using only 5 watts of power. I understand the repeater is different than the digi, so perhaps that doesn't really mean anything. Heck, I was running 5 watts of power on voice thru the W4IAX repeater all the way from home to work on the VX-150 I was using, but now with the D700A I'm running 10 watts of power on voice, but 50 watts of power on APRS. I started using only 10 watts, but didn't get to the Igate very often, so upped the power to 50 watts and that helped some.
</div>

<div>I'm sorta looking forward to a trip - perhaps this weekend? - to see how I am digi'd with repeaters from out of area. Since the local IGate is in Pensacola, perhaps tomorrow I will take a ride over toward Gulfport, MS and see how I'm digi'd thru those repeaters? That might tell me something.

<div>Yes, if you check my track you can see up around the I-10 area is where I'm not very often digi'd - and that is where the W4IAX should be doing the digi'ing as it is so close. </div>
<div> </div>
<div>A bit of a hassle to remove the radio from the bike and use in a car - even on a temp basis. Before mounting on the bike, I did use the radio here in the house and it was the KI4ELU digi that would pick me up then, not the W4IAX.

<div>Thanks for the suggestions and ideas..... any other ideas or suggestions?</div>
